MANILA, Philippines Chinese navy ships avoided a possible maritime standoff by safely removing one of the country's warships Sunday from a disputed shoal off the western Philippines where it had run aground while on a security patrol.

A cyber spy network based mainly in China hacked into classified documents from government and private organizations in 103 countries, including the computers of the Dalai Lama and Tibetan exiles, Canadian researchers said Saturday.

As China and the U.S. traded new accusations Tuesday over this week's incident in which Chinese vessels harassed a U.S. Navy ship, nearly causing a collision at sea, experts on China tried to decipher just how serious the episode was.
